        Note.--Includes $1,712 million in budget authority in 2002 for
    activities previously financed from:
                                                  2000           2001
    Mission Support (in millions of dollars)         1,566           1,715

        This appropriation provides funding for Human Space Flight (HSF)
    activities, and for Safety, mission assurance and engineering activities
    supporting the Agency. The HSF activities include development and
    operations of the Space Station, the Space Station research program, and
    operation of the Space Shuttle. This includes development of contingency
    capabilities for the Space Station, high priority investments to improve
    the safety of the Space Shuttle, and required construction projects in
    direct support of Space Station and Space Shuttle programs. This
    appropriation also provides for salaries and related expenses; design,
    repair, rehabilitation, and modification of facilities and construction
    of new facilities; maintenance, and operation of facilities; and other
    operations activities supporting human space flight programs; and space
    operations, safety, mission assurance and engineering activities that
    support the Agency.

        In FY 2000 and FY 2001, the Human Space Flight (HSF) account
    provided only for the direct funding of human space flight activities;
    space operations services had been funded within the Science,
    Aeronautics and Technology (SAT) account; and Safety, mission assurance
    and engineering had been funded within the Mission Support account.
    Beginning

    [[Page 1062]]

    in FY 2002, other than direct costs (which includes Research and Program
    Management and non-programmatic Construction of Facilities) will be
    allocated to either the HSF or the SAT account based on the number of
    full time equivalent people, and there will no longer be a Mission
    Support account.

    Performance Objectives

        Space station.--The International Space Station (ISS) is an
    international laboratory in low Earth orbit on which American, Russian,
    Canadian, European, and Japanese astronauts will conduct unique
    scientific and technological investigations in a microgravity
    environment. The goal of the Station is to support activities requiring
    the unique attributes of humans in space and establish a permanent human
    presence in Earth orbit. The proposed budget provides funding for the
    continued development of the vehicle and its research components and for
    current operations, assembly and utilization of the station. With
    several assembly missions successfully completed, the budget includes
    funding to keep subsequent assembly missions on schedule through U.S.
    Core Station Complete, currently planned for late 2003-early 2004, and
    for early research commensurate with the build-up of on-orbit
    utilization capabilities and resources.

        Between January 2000 and January 2001, the Russian Service Module,
    the Z1 and SO trusses, the control moment gyros, the first photo-voltaic
    array and battery sets, initial thermal radiators, communication
    equipment, and the U.S. Laboratory were assembled on-orbit. A permanent
    human presence in space was achieved with the launch of Expedition 1.
    The first phases of multi-element integrated testing (MEIT) were
    completed. Crew training, payload processing, hardware element
    processing, and mission operations were supported. During the remainder
    of 2001, Expedition 2 will be deployed, and Phase 2 of the station
    assembly will be completed with the launch of the airlock. Preparations
    will continue for the start of Phase 3 and the first shuttle mission
    dedicated to research utilization is expected to be launched in mid-
    2002.

        Russian Program Assurance (RPA) is contained within the Space
    Station budget and provides funding for contingency activities to
    address ISS program requirements resulting from delays or shortfalls on
    the part of Russia in meeting its commitments to the ISS program. Key
    elements of the RPA program have been the Interim Control Module (ICM),
    developed by the U.S. Naval Research Laboratory (NRL), and the U.S.
    Propulsion Module. With the successful launch of the Russian Service
    Module, and escalating costs for Space Station, including RPA
    components, NASA reassessed its Space Station priorities and the need
    for planned RPA hardware. In FY 2000, the ICM was placed in ``call-up''
    mode and stored at NRL. Work on the original Propulsion Module design
    was terminated, and in FY 2001 funds for the Propulsion Module were
    redirected to cover cost increases in the baseline program. This left
    logistics contingency funding and funds for potential procurement of
    safety-related Russian goods and services in the RPA budget. Based on
    recent operational experience, continuing flight software and hardware
    integration issues, obsolescence issues, and realization that earlier
    assembly phase cost estimates were low, NASA concluded that the program
    baseline could not be executed on schedule within approved funding
    levels. A reassessment of the ISS Program budget baseline was started in
    FY 2000 and continued into FY 2001. The initial results, based on
    conservative estimating assumptions, showed a budget shortfall of up to
    $4 billion over 5 fiscal years. To remain within the Agency's budget
    marks, NASA redirected funds from remaining high-risk, high-cost
    hardware development, including the Habitation Module and Crew Return
    Vehicle (CRV), as well as funds from the RPA budget mentioned above, to
    ensure that ISS would stay within budget, while assembly continues
    though U.S. Core Station Complete (deployment of Node 2 on flight 10A).
    This will allow for the integration of flight hardware being provided by
    the International Partners. In addition, the ISS Research Program is
    being realigned to match the on-orbit capability build-up as the program
    moves toward U.S. Core Complete. NASA will continue to pursue
    atmospheric testing of the X-38 and is assessing the affordability of
    completing the space flight test relative to other program priorities.
    Options for provision of a crew return capability and Habitat capability
    to support the desired increase in crew size from 3 to 6 will be
    discussed with the international partners. However, U.S. contributions
    to such capabilities will be dependent on the availability of funds
    within the President's five-year budget plan for Human Space Flight,
    technical risks, and the Administration's confidence in Agency cost
    estimates.

        Over the next several years, the Agency will press ahead with ISS
    assembly and the integration of the partners' research modules. Research
    operations on board the ISS have been expanding since they began in FY
    2000 and will greatly exceed any previous capabilities for research in
    space including Skylab, Shuttle, or Mir.

         Payload and Expendable Launch Vehicle (ELV) support.-- During 2001,
    six pallets will be used in Space Shuttle missions. In FY 2001 and FY
    2002, over 20 major and secondary payloads will be supported, including
    major hardware for ISS assembly. The ELV Mission Support budget provides
    funds for acquiring requisite launch services to meet all NASA
    requirements and for technical insight of commercially provided launch
    services. Advanced mission design/analysis and leading edge integration
    services are provided for the full range of NASA missions under
    consideration for launch on ELVs. During FY 2000, six ELV missions were
    successfully launched. Integration and technical management of 13
    missions are planned for launch in FY 2001. In FY 2002 support for eight
    missions is planned.

        Investments and support.--The Human Exploration and Development of
    Space (HEDS) Technology and Commercialization Initiative (HTCI) began in
    FY 2001. HTCI will continue in FY 2002 to focus on human space
    exploration and development activities emphasizing highly innovative
    technologies, advances in science, and enabling synergistic commercial
    space development efforts.

        Project activity will continue in FY 2002 to ensure NASA's rocket
    propulsion test capabilities are properly managed and maintained in
    world class condition. The project will significantly enhance our
    ability to properly manage NASA's rocket testing activities and
    infrastructure across all four participating NASA centers.

        Engineering and technical base (ETB) activity will continue to
    support the institutional capability in the operation of space flight
    laboratories, technical facilities, and testbeds; to conduct independent
    safety, and reliability assessments; and to stimulate science and
    technical competence in the United States.

        Funding for other direct costs associated with Human Space Flight,
    which were previously funded in the Mission Support account, are now
    funded as part of investments and support. This includes research and
    program management costs and non-programmatic construction of facilities
    costs.

        Space shuttle.--The Space Shuttle is a partially reusable space
    vehicle that provides several unique capabilities to the United States
    space program. These include retrieving payloads from orbit for reuse,
    servicing and repairing satellites in space, safely transporting humans
    to and from space, launching ISS components and providing an assembly
    platform in space, and operating and returning space laboratories. In FY
    2000, the Space Shuttle launched four flights success

    [[Page 1063]]

    fully including the emergency HST Servicing Mission 3A which replaced
    failing gyros on the HST and the Shuttle Radar Topography Mission
    (SRTM), a joint DOD/NASA payload to study the earth. The Space Shuttle
    also visited the ISS two more times, for both assembly and maintenance.

        Seven flights are planned during FY 2001, all of which are ISS
    assembly and servicing missions. The first crew began permanent
    occupation and presence aboard the ISS in FY 2001. In FY 2002, seven
    flights are planned including a dedicated microgravity research flight
    and another HST Servicing Mission (HST-3B) and five ISS assembly and
    servicing missions.

        Space operations.--The primary goal of space operations is to
    provide highly reliable and cost-effective space operations services in
    support of NASA's science and aeronautics programs. In addition, support
    is provided to interagency, international, and commercial space-faring
    enterprising on a reimbursable basis. The Space Communications program
    is composed of Operations, Mission and Data Service Upgrades, Tracking
    and Data Relay Satellite Replenishment, and Technology Projects, as well
    as spectrum management and data standards coordination. Services are
    provided to a large number of NASA missions including planetary and
    interplanetary missions; human space flight missions, near-earth and
    earth orbiting missions; and sub-orbital and aeronautical flight tests.
    A Consolidated Space Operations Contract (CSOC) was successfully
    implemented by the Space Operations Management Office at Johnson Space
    Center and the Lockheed Martin Space Operations Company. The CSOC
    provides end-to-end mission and data services to both NASA and non-NASA
    customers. A total of nine contracts have been consolidated to date, and
    seven further contracts are to be consolidated in FY 2001 and FY 2002.
    Management responsibility for all Wide Area Network data distribution
    services for all human space flight, earth orbiting and deep space
    missions and NASA administrative communications was outsourced by CSOC
    in FY 2000. Development of the TDRS Replenishment Spacecraft is ongoing,
    with the first satellite launched in FY 2000.

        Safety, mission assurance and engineering.--The goal of this program
    is to invest in the safety and success of NASA missions by assuring that
    sound and robust policies, processes, and tools for safety, reliability,
    quality assurance, and engineering disciplines are in place and applied
    throughout NASA. The program also examines long-term technology
    requirements for NASA's strategic objectives.

        The FY 2003 budget estimate for this account is $6.9 billion.

        Note.--Includes $1,029 million in budget authority in 2002 for

                                                  2000           2001
    Mission support (in millions of dollars)           856             887

        This appropriation provides for the science, aeronautics and
    technology (SAT) supporting the Agency. The SAT activities include space
    science, biological and physical research, earth science, aerospace
    technology, and academic programs. This appropriation also provides for
    salaries and related expenses; design, repair, rehabilitation, and
    modification of facilities and construction of new facilities;
    maintenance and operation of facilities; and other operations activities
    supporting science, aeronautics, and technology programs.

        In FY 2000 and FY 2001, the SAT account provided only for the direct
    funding of science, aeronautics and technology activities, and included
    funding for space operations services which are now funded within the
    human space flight account. Beginning in FY 2002, other direct costs
    (which include Research and Program Management and non-programmatic
    Construction of Facilities) will be allocated to either the HSF or the
    SAT account based on the number of full time equivalent personnel, and
    there will no longer be a Mission Support account.

    Performance Objectives

        Space science.--The Space Science program seeks to answer
    fundamental questions concerning: the galaxy and the universe; the
    connection between the Sun, Earth and heliosphere; the origin and
    evolution of planetary systems; and the origin and distribution of life
    in the universe. The Space Science program is comprised of a base
    program of' research and development activities, including research and
    flight mission activities, and major space-based facilities.

        In 2000, the Space Science program produced many notable scientific
    accomplishments. Scientists using data from NASA's Mars Global Surveyor
    spacecraft camera found features that suggest there may be current
    sources of liquid water at or near the surface of the red planet. The
    water supply may be about 100 to 400 meters (300 to 1,300 feet) below
    the surface, and limited to specific regions across the planet.
    Additional MGS images revealed layers of sedimentary rock that paint a
    portrait of an ancient Mars that long ago may have featured numerous
    lakes and shallow seas. These regions of sedimentary layers on Mars are
    spread out and scattered around the planet.

        Solar and Heliospheric Observatory (SOHO) scientists have, for the
    first time, imaged solar storm regions on the side of the Sun facing
    away from the Earth. A week's advance warning of potential bad weather
    in space is now possible thanks to these SOHO measurements. Detailed
    images from the Transition Region and Coronal Explorer (TRACE) mission
    of giant fountains of fast-moving, multimillion-degree gas in the
    outermost atmosphere of the Sun have revealed an important clue to a
    long-standing mystery--the location of the heating mechanism that makes
    the corona 300 times hotter than the Sun's visible surface. Scientists
    are interested in the corona, which appears as a halo of light seen by
    the unaided eye during a total solar eclipse, because eruptive events in
    this region can disrupt high-technology systems on Earth. Astronomers
    also hope to use the solar corona studies to better understand other
    stars.

        The balloon-borne BOOMERANG sub-millimeter telescope mapped the
    faint light left over from the Big Bang, revealing the earliest
    structure in the Universe that later became the vast, soap bubble-shaped
    clusters of galaxies that astronomers observe today. BOOMERANG confirmed
    that the Universe is flat (Euclidean) and that the expansion of the
    universe is accelerating.

        The Shoemaker Near Earth Asteroid Rendezvous (NEAR) mission became
    the first spacecraft to orbit an asteroid on February 14, 2000. The
    mission has returned stunning images and other data of the asteroid
    Eros, resulting in numerous discoveries throughout the year. Most
    recently, NEAR made history again by becoming the first spacecraft ever
    to touch down on the surface of a small solar system body.

        Scientists used the Chandra X-ray Observatory to examine a mid-mass
    black hole in the galaxy M82. This black hole may represent the missing
    link between smaller stellar black holes and the supermassive black
    holes found at the centers of galaxies. A Hubble Space Telescope census
    finds that the mass of a supermassive black hole is directly related to
    the size of a the bulge of stars at the center of its host galaxy. This
    suggests that the evolution of galaxies and their host black holes is
    intimately linked.

        The Cassini spacecraft, on its way to meet Saturn in 2004, flew by
    Jupiter in December and performed joint science operations with Galileo.

        The Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) was
    successfully launched in March 2000, and has provided the first large-
    scale pictures of the Earth's magnetic field.

        The NASA budget request for FY 2002 funds a robust program of Mars
    exploration for the next decade. Following the loss of the Mars Climate
    Orbiter and the Mars Polar Lander in 1999, an in-depth review of our
    Mars exploration program found significant flaws in program formulation
    and execution, and made recommendations for the future exploration of
    Mars. Consistent with those recommendations, we are pressing forward
    with the development of a set of future Mars missions to establish a
    sustained presence at Mars. By means of orbiters, landers, rovers and
    sample return missions, NASA's revamped campaign to explore Mars is
    poised to unravel the secrets of the red planet's past environments, the
    history of its rocks, the many roles of water and, possibly, evidence of
    past or present life. The Mars Global Surveyor entered Mars orbit in
    September 1997, and is still performing flawlessly. The 2001 Mars
    Odyssey will be launched in April 2001, and we have started development
    of the twin Mars Environmental Rovers for launch in 2003. Additional
    Mars Exploration Program funding provided in the President's FY 2002
    Budget will enable: a robust 2005 Mars Reconnaissance Orbiter; a
    competitively selected 2007 Mars Scout mission; an accelerated 2009 Mars
    Mobile Laboratory mission; U.S. participation in foreign missions to
    Mars; and technologies for the next decade of robotic Mars missions.

        Development activities continue on the Relativity (Gravity Probe-B)
    mission, which is now scheduled for launch in 2002, and the Space
    Infrared Telescope Facility (SIRTF), with launch planned for July 2002.
    Launch of the Thermosphere, Ionosphere, Mesosphere Energetics and
    Dynamics (TIMED) mission is expected to occur this summer (2001).
    Development activities on the Stratospheric Observatory for Infrared
    Astronomy (SOFIA) continue. Funding for the Hubble Space Telescope (HST)
    continues to support operations and preparations for the last planned
    Hubble servicing missions, servicing mission 3B in early FY 2002 and
    servicing mission 4 in FY 2004, when new science instruments will be
    installed.

        In the Explorer program, development activities continue for the
    Microwave Anisotropy Probe (MAP), which will be launched in summer 2001;
    the Full-sky Astrometric Mapping Explorer (FAME), scheduled for launch
    in 2004, and Swift, a multi-wavelength observatory for gamma-ray burst
    astronomy, to be launched in 2003. Three Small (SMEX) missions continued
    development in FY 1999: the High Energy Spectroscopic Imager (HESSI) is
    to launch in spring 2001; the Galaxy Evolution Explorer (GALEX) will
    launch in early FY 2002; and the Two Wide-Angle Neutral Atom
    Spectrometers (TWINS) will be launched in 2002 and 2004.

        In the Discovery program, the fourth mission, Stardust, was launched
    on schedule in February 1999, and is operating normally during its
    cruise to comet Wild-2, with the encounter scheduled for 2004. Two
    Discovery missions selected in 1997 are proceeding: the Comet Nucleus
    Tour (CONTOUR) began development in CY 2000 and will be launched in
    2002; the Genesis solar wind sample return mission has nearly finished
    development and will be launched in summer 2001. Two new missions were
    selected for implementation during 1999: The MErcury Surface, Space
    ENvironment, GEochemistry and Ranging (MESSENGER) mission to orbit
    Mercury; and the Deep Impact mission to fly by and fire an impactor into
    a comet. Both MESSENGER and Deep Impact are planned for launch in 2004.

        The New Millennium program is providing flight demonstrations of
    critical new technologies which will reduce the mass and cost of future
    science and spacecraft subsystems, while maintaining or improving
    mission capabilities. In 1999, NASA selected the Nanosat Constellation
    Trailblazer as the Space Technology-5 New Millennium mission. This
    mission will feature three very small satellites (each about the size of
    a large birthday cake), that will fly in formation and test eight
    technologies in the harsh space environment near the boundary of Earth's
    protective magnetic field. The Flight Validation program has been
    restructured to enhance openness and competition as well as to increase
    the number of opportunities for technologies to be flight-validated. An
    Announcement of Opportunity for Space Technology-6 technologies was
    recently released, and in January 2001, eight teams from industry,
    universities and NASA centers were selected to develop new technology
    concepts, such as advanced solar power and optical communications, for
    future NASA missions. The teams will study flight test options during a
    six-month phase for defining the technology concepts. NASA then plans to
    select up to five of the concepts for Space Technology-6 (ST-6), the
    next New Millennium Program project, which will flight-test the new
    technology concepts in 2003 and 2004.

        The President's FY 2002 Budget also provides funding for a new
    Planetary Propulsion program. This program will competitively develop
    advanced propulsion systems that will reduce the flight time for future
    robotic missions to the planets and other science targets in the solar
    system.

        Biological and Physical Research.--In FY 2001, the Office of
    Biological and Physical Research (OBPR) was created as an independent
    research organization and a fifth strategic enterprise, by the
    restructuring of the Office of Life and Microgravity Sciences and
    Applications (OLMSA). The Enterprise uses the unique environment of
    space to understand the effect of gravity on biological systems and to
    conduct research in the areas of fluid physics, combustion science,
    fundamental physics, materials science and biotechnology.

        In FY 2000, Space Shuttle Mission STS-101 flew two commercial
    research payloads which grew large biological crystals in space and
    investigated the effects of microgravity on the efficiency of
    genetically transforming plant seeds. Also during FY 2000, the Protein
    Crystal Growth-Enhanced Gaseous Nitrogen Dewar (PCG-EGN), was used
    aboard ISS to crystallize proteins for later analysis.

        In FY 2001, the first rack of the Human Research Facility (HRF) will
    be deployed to the International Space Station, and OBPR will begin
    initial operations of this facility. Construction continues on the
    Booster Applications Facility at Brookhaven National Laboratory. In FY
    2001, research in bioastronautics increased to accelerate development of
    countermeasures that will improve the health and safety of astronauts
    aboard the International Space Station (ISS). Devices and
    countermeasures developed through this initiative may also have many
    health benefits on Earth. The first four commercial research payloads,
    investigating antibiotic production, protein crystal growth,
    agricultural research, and materials research, will be flown on the
    International Space Station in FY 2001.

        During FY 2002, OBPR will continue to demonstrate key technology
    capabilities for human support, such as advanced techniques for water
    processing, solid waste processing, air revitalization, biomass
    production, food processing, and thermal control. In addition, the
    office will continue work in fundamental biology and bioastronautics to
    increase knowledge and address critical questions in crew health and
    safety by conducting investigations on the Space Shuttle and ISS. These
    will include investigations of the effect of microgravity on skeletal
    myofibers, avian development in space, the effects of microgravity on
    bone as a function of age, changes in gene expression in bacteria in
    space, and the effects of gravity on plant photosynthesis and
    respiration. New research projects will be selected in the areas of
    biotechnology, fluid

    [[Page 1066]]

    physics, and materials science, and commercial payloads will be flown on
    both the Shuttle and aboard ISS.

        Earth Science.--The mission of NASA's Earth Science Enterprise (ESE)
    is to develop a scientific understanding of the Earth system and its
    response to natural and human-induced changes to enable improved
    prediction of climate, weather and natural hazards for present and
    future generations. ESE seeks to answer a question of fundamental
    importance to science and society: How is the Earth system changing, and
    what are the consequences for life on Earth? To do so ESE is developing
    the interdisciplinary research field of Earth System Science, which
    recognizes that the Earth's land surface, oceans, atmosphere, ice
    sheets, and life itself all interact in a highly dynamic system. Earth
    system science is an area of research with immense benefit to the
    Nation, leading to new knowledge and tools that may improve weather
    forecasting, agriculture, urban and regional planning, environmental
    quality, and natural disaster management. ESE has established three
    goals to pursue in order to fulfill its mission: (1) Science--observe,
    understand, and model the Earth system to learn how it is changing, and
    the consequences for life on Earth; (2) Applications--expand and
    accelerate the realization of economic and societal benefits from Earth
    science, information, and technology; (3) Technology--develop and adopt
    advanced technologies to enable mission success and serve national
    priorities.

         In ESE Science, 2000 was another year of substantial accomplishment
    toward understanding the Earth system. In an 11-day Space Shuttle
    mission, a new inteferometric synthetic aperture radar technique
    collected data sufficient to produce the first detailed topographic map
    of the entire land surface of the Earth between 60+N and 56+S. Landsat 7
    completed a global survey of land cover, and the Terra satellite
    observed the global land and ocean biosphere as it underwent seasonal
    changes, and showed that snow cover over North America was substantially
    below normal following the warmest winter on record. The QuikSCAT
    satellite observed a Connecticut-size iceberg break off of the Antarctic
    polar ice sheet, and the US and Canada mapped Antarctica for the second
    time with space-based radar in order to compare with the first and
    determine rates of change. Using data from the US/Japan Tropical
    Rainfall Measuring Mission, researchers determined that air pollution
    affects rainfall rates downwind of its sources. Also in 2000, ESE
    formulated a new Research Strategy for 2000-2010 to guide research over
    the next decade, identifying 23 societally important research questions
    in the Earth system paradigm of variability, forcing, response,
    consequence and prediction. This Research Strategy will guide ESE's
    science activities and investments over the next decade.

         In ESE Applications, ESE has entered into a variety of partnerships
    that will demonstrate the goods and services made possible by ESE's
    research. ESE provides QuikSCAT data in real time to NOAA to improve
    marine weather forecasting, and has used these data to show that severe
    storms forming over the oceans can be predicted two days in advance. ESE
    is working with FEMA to use remote sensing tools to update their flood
    plain maps throughout the US. In a partnership called AG 2020 with USDA
    and four growers associations representing 100,000 farmers, ESE is
    demonstrating how to increase crop productivity, reduce risks to crop
    health, and manage environmental impacts. With the National Institutes
    of Health, we are exploring the use of satellite data to predict spread
    of infectious diseases such as malaria that are highly influenced by
    weather and climate. Throughout the summer, three ESE satellites tracked
    devastating wildfires in the western US, providing data to the US Forest
    Service and regional authorities. ESE held three regional workshops
    across the US to plan the next generation of applications demonstration
    projects with State and local governments in infrastructure planning and
    related topics.

         In ESE Technology, the Enterprise launched its first New Millennium
    Program satellite to demonstrate a variety of new technologies for Earth
    Science. These include a new instrument to produce a Landsat-type sensor
    one-fourth the size of the current Landsat 7 instrument, and the first
    hyperspectral imager in space, which views the land surface in hundreds
    of spectral channels rather than the conventional 5 to 7. Sponsored
    technology research with universities, industry and other government
    laboratories moved 20 different remote sensing instrument concepts one
    step closer to reality on an established scale of technology maturity.
    These will substantially reduce the cost and enhance the capability of
    new satellites over the next decade or more.

         ESE is in the midst of deployment of the Earth Observing System
    (EOS), a set of spacecraft and associated interdisciplinary science
    investigations to initiate a long-term data set of key parameters
    required for the study of global climate change. The first four EOS
    satellites are already in orbit, including the flagship Terra mission
    launched in 1999. The remaining EOS satellites will be launched through
    2003, including Aqua (2001) to study the water cycle and atmospheric
    circulation, and Aura (2003) to probe the chemistry of the upper and
    lower atmosphere. Complementing EOS is a series of small, focused Earth
    System Science Pathfinder missions to explore Earth system processes
    never before examined globally from space. Data from the EOS satellites
    already in orbit are being acquired, processed, and distributed by the
    EOS Data and Information System (EOSDIS), which is currently handling
    more than 1 terabyte of data per day. EOSDIS handled 1.5 million user
    queries for over 8 million products in 2000. EOSDIS continues to evolve
    as new satellites are launched, and as new partners are added to produce
    data products with innovative applications.

         As it deploys EOS, ESE is also planning for the future. For
    example, a Landsat Data Continuity Mission is being formulated in
    partnership with USGS, and will be implemented as a commercial data
    purchase, if possible. ESE is also planning for the transition of
    several of its key research observations to the Nation's weather
    satellite system. The DoD, NOAA and NASA have established an Integrated
    Program Office (IPO) to create a converged civilian and military weather
    satellite system called the National Polar-orbiting Operational
    Environmental Satellite System (NPOESS) to replace the present
    generation of separate systems. NASA and the IPO are jointly funding the
    NPOESS Preparatory Project (NPP) that will simultaneously continue key
    measurements begun by EOS and demonstrate instruments for NPOESS. The
    NPP will save money for both organizations by combining essential
    atmospheric and Earth surface observations on a single platform, and by
    seeking to meet both climate science and operational weather
    requirements with the same advanced instruments.

        ESE data products and research are a major contribution to the US
    Global Change Research Program, an interagency collaboration overseen by
    the Committee on Natural Resources of the National Science and
    Technology Council. Because Earth science is inherently global in scope,
    ESE is engaged in a variety of international partnerships with
    individual nation's space agencies, and with international consortia
    such as the World Meteorological Organization. ESE seeks and receives
    scientific advice on a broad range of topics from the various boards and
    committees of the National Research Council. These partnerships,
    together with those above, ensure that NASA's Earth Science Enterprise
    conducts research at the frontiers of Earth science on questions of
    practical importance to the Nation.

        Aerospace Technology.--The mission of this Enterprise is to pioneer
    the identification, development, verification, transfer, application,
    and commercialization of high-payoff aerospace technologies. Through its
    research and technology accomplishments, Aerospace Technology promotes
    economic growth and national security by supporting a safe, efficient
    national aviation system and affordable, reliable space transportation.
    In addition, the Aerospace Technology Program supports the development
    of crosscutting technology to serve the needs of all NASA Enterprises.
    To meet this challenge, the Enterprise has established three main
    technology goals and one goal for commercialization. Within the three
    technology goals a set of objectives has been defined to address current
    and future National needs. The technologies associated with these
    objectives are pre-competitive, long-term, high-risk research endeavors
    with high payoff in terms of market growth, safety, low acquisition
    cost, consumer affordability and a cleaner environment. The first goal,
    Revolutionize Aviation, addresses the fundamental, systemic issues in
    the aviation system to ensure continued growth and development
    appropriate to the needs of the national and global economies. These
    systemic issues--safety, capacity, environmental compatibility, and
    mobility--cut across markets including large subsonic civil transports,
    air cargo, commuter and general aviation. NASA coordinates its
    investments and technology objectives in this area with the Federal
    Aviation Administration and the Department of Defense through the
    National Research and Development Plan for Aviation Security,
    Efficiency, and Environmental Compatibility. The second goal, Advance
    Space Transportation, will create a safe, affordable highway through the
    air and into space by improving safety, reliability, and operability,
    while significantly reducing the cost of space transportation systems.
    With the creation of the Integrated Space Transportation Plan (ISTP),
    NASA defined a single, integrated investment strategy for all its
    diverse space transportation efforts. The third goal, Pioneer Technology
    Innovation, is unique in that it focuses on broad, crosscutting
    innovations critical to a number of NASA missions and to the aerospace
    industry in general. Pursuing technology fields that are in their
    infancy today, developing the knowledge bases necessary to design
    radically new aerospace systems, and developing tools for efficient,
    high-confidence design and development, will enable a revolution in
    aerospace. The fourth goal, Commercialize Technology, is to extend the
    commercial application of NASA technology for economic benefit and
    improved quality of life. By partnering with both aerospace and non-
    aerospace industry as well as academia, the full range of NASA's
    assets--technological expertise, new technologies, and research
    facilities--are made available to help the Nation.

        As planned in the FY 2001 budget request, the Administration's 2002
    request includes an increase in funding for the 2nd Generation Reusable
    Launch Vehicle (RLV) Program, although this request is lower than last
    year's projections primarily due to reallocation of Crew Return Vehicle
    placeholder funding to the International Space Station. Low-cost space
    transportation remains the key enabler for a more aggressive civil space
    program. NASA's Integrated Space Transportation Planning activities have
    identified a strategy based upon competition, safety, industry
    leadership and affordable requirements. Funding supports aggressive
    technical risk reduction and advanced development for multiple reusable
    launch vehicle concepts. Identification and preliminary development of
    NASA-unique systems and near-term pursuit of technologies required for
    alternative access for key Space Station needs are also both critical
    elements of the Integrated Space Transportation Plan (ISTP). All of
    these efforts combined will move NASA closer to a full and open RLV
    competition in the middle of this decade to meet NASA's human space
    flight needs by the end of the decade. In FY 2001, NASA will make the
    first risk reduction activity awards to industry under the 2nd
    Generation RLV Program. These risk reduction activities will continue
    through FY 2002 and feed future steps toward the launch services
    competition at mid-decade. The President's FY 2002 Budget prescribes
    several key management reforms in areas like vehicle requirements and
    program integration that will help ensure the success of this important
    undertaking.

        The Administration's request includes a significant investment in
    computing and information technology developments and also increases the
    investment in biotechnology and nanotechnology--the revolutionary
    technologies of the 21st Century. To ensure the highest quality research
    and strong ties to NASA's mission, these investments will be guided by
    technology development agreements signed by customers in other NASA
    Enterprises and subject to external, independent reviews. A significant
    portion of these investments will be externally competed. The
    Administration's request supports the implementation of six University-
    based Research, Education, and Training Institutes (RETIs). This will
    strengthen NASA's ties to the academic community through long-term
    sustained investment in areas of science and technology critical to
    NASA's future. To ensure the highest quality research and training and
    infusion of new ideas, these RETIs will be subject to independent,
    external reviews and recompetition at regular intervals, including
    mandatory sunsets after ten years. The Administration's request also
    supports a 21st Century aerospace vehicle technology program. This
    research will develop and verify critical technologies that provide
    leapfrog capabilities for aerospace vehicles that will be able to change
    their shape in flight like birds to optimize performance or perform
    complex maneuvers in complete safety, and be capable of self repair when
    damaged.

        The President's request for NASA maintains investments in technology
    development activities that will address the challenges (safety,
    environmental impact, capacity, and noise reduction) that face the
    Nation's air system. As part of NASA's response to the national goal of
    reducing aircraft accidents by a factor of 5 by the end of FY 2007, NASA
    began a focused Aviation Safety Program (AvSP) in FY 2000 that builds on
    the extensive safety related activities of the Base Research and
    Technology (R&T) Programs. The base technologies provided the foundation
    for focused safety development efforts in the future, as well as some
    near-term achievements. For example, in FY 2000, AvSP produced an icing
    training program for general aviation and commuter pilots, completed a
    flight evaluation of an initial national capability for digital data
    link and graphical display of weather information, and demonstrated a
    concept for the integration of air traffic control runway incursion
    information onto aircraft flight deck displays. In FY 2001, the AvSP
    will complete a laboratory demonstration of a fuel system modification
    to reduce flammability, define the architecture for an integrated
    onboard health management system, and down-select synthetic vision
    concepts suitable for retrofit in commercial, business, and general
    aviation aircraft. The Base R&T Programs will continue to develop the
    technologies that will contribute to the FY 2007 goal. For example, in
    FY 2002, NASA will complete an interim progress assessment utilizing the
    technology products of the Aviation Safety program as well as related
    Aerospace Base R&T efforts to demonstrate potential to meet the National
    Goal.

        NASA also continued its efforts to reduce the environmental impact
    associated with aviation systems. The Ultra Efficient Engine Technology
    (UEET) program is a focused program that began in FY 2000. UEET is
    planned and designed to develop high-payoff, high-risk technologies to
    enable the next breakthroughs in propulsion systems and to spawn a new
    generation of high-performance, operationally efficient and economical,
    reliable and environmentally compatible U.S. air

    [[Page 1068]]

    craft. In FY 2002, UEET will, in sector combustor tests, demonstrate
    initial 70% low NOx reduction, relative to 1996 International Civil
    Aviation Organization (ICAO) standards for Landing/Takeoff conditions in
    subsonic engines. Similarly, progress is being achieved in noise
    abatement efforts. In 2000, NASA validated the technologies required to
    reduce community noise impact by up to 10 dB relative to 1992
    technology. In FY 2001 and FY 2002, NASA will: select engine system and
    airframe system technologies necessary to achieve a 3-dB aircraft system
    noise reduction beyond the 1997 baseline, establish the influence of
    wind and temperature gradients on community noise impact, and release
    the beta version of an improved advanced noise prediction code. Also in
    FY 2002, source diagnostics tests will be completed, giving engine
    component designers insight into the fundamental physics of the
    mechanisms that generate broadband fan noise. The data generated by
    these tests will be used to improve the computational algorithms used in
    computer codes to predict engine noise. The design of an advanced
    concept for reduced jet noise will be initiated for testing at
    laboratory scale later in the Quiet Aircraft Technology program.

        In FY 2000, NASA's Aviation System Capacity program demonstrated
    technologies in a realistic Terminal Area environment, achieving a 12-
    15% increase in single-runway throughput and proving the ability to
    space aircraft closer than 3,400 feet on parallel runways while meeting
    all Federal Aviation Administration (FAA) safety criteria. In FY 2001,
    NASA will demonstrate transition airspace decision support tools for:
    (1) Air Traffic Control (ATC)/airline operations center and ATC/cockpit
    information exchange, and (2) conflict resolution. In FY 2002 NASA will
    demonstrate an interoperable suite of at least two decision support
    tools for arrival, surface and departure operations and begin an
    activity entitled AvSTAR which will undertake a Virtual Airspace
    Modeling project to produce a high-fidelity computer model of the
    Nation's aviation system. This model will help the FAA and NASA develop
    new operational concepts and better understand the benefits of new
    technologies for reducing aviation system congestion and delays while
    improving aviation safety.

        Building on its world-record-setting performances, the Environmental
    Research Aircraft and Sensor Technology (ERAST) project modified the
    Centurion solar-powered remotely piloted aircraft (RPA) to a wingspan
    configuration of greater than 245 feet, renamed the aircraft Helios, and
    continued flight testing in FY 2000. This configuration will be more
    suitable for extreme endurance as well as short flights to the 100,000
    ft. altitude. In FY 2001, the Flight Research program will demonstrate a
    solar-powered RPA at 100,000 ft and complete development of a
    heavyweight energy storage system under the ERAST project. Both
    achievements will demonstrate technologies that will provide atmospheric
    satellites for commercial use, disaster relief efforts such as
    communication relays and real time sensing, and will increase the
    Nation's capability to make scientific sampling high in the atmosphere.
    In FY 2002 flight validation of an experimental, consumable fuel, RPA
    design will enable an enhanced prototype vehicle that meets the
    prescribed set of Earth Science RPA platform requirements.

        The Commercial Technology Program's focus in FY 2000 was continued
    investment of 10-20 percent of the NASA R&D budget in commercial
    partnerships with industry and a more efficiently administered program.
    Based on experience to date, these commercial partnerships are expected
    to increase the return on the Government's R&D investment, allowing NASA
    to do more with limited funds, and strengthening the international
    competitiveness of key industry sectors. In FY 2001 and 2002, the
    program will continue to emphasize innovative commercial partnerships
    with industry and continue to refine and enhance a technology and
    partnership database. In addition, the Small Business Innovative
    Research programs will pursue increased use and expanded commercial
    application of the developed technology.

        Academic programs.--The goal of Academic Programs is educational
    excellence: NASA involves the educational community in our endeavors to
    inspire America's students, create learning opportunities, and enlighten
    inquisitive minds. NASA's Education Program brings students and
    educators at all levels into its missions and its research as
    participants and partners, providing opportunities for a diverse group
    of educators and students to experience first hand involvement with NASA
    personnel, facilities, and research and development activities. Academic
    Programs includes the Minority University Research Program, with a goal
    to expand NASA's research base by strengthening the research
    capabilities of minority universities and colleges; to contribute to the
    scientific and technological workforce; and to promote educational
    excellence. The range of activities conducted under this program will
    continue to capture the interest of all students in science and
    technology, develop talented students at the undergraduate and graduate
    levels, provide research opportunities for students and faculty members
    at NASA centers, and strengthen and enhance the research capabilities of
    the Nation's colleges and universities.

        The 2003 budget estimate for this account is $8.1 billion.

    ---------------------------------------------------------------------------
        Note.--Excludes $2,741 million in budget authority in 2002 for
    activities transferred to Human Space Flight and Science, Aeronautics
    and Technology. Estimated comparable amounts for 2000 ($2,422 million)
    and 2001 ($2,602 million) are included above.

        In FY 2000 and FY 2001, this appropriation provides funding for
    mission support and includes: safety, mission assurance, engineering and
    advanced concepts activities supporting agency programs; salaries and
    related expenses in support of research in NASA field installations;
    design, repair, rehabilitation and modification of institutional
    facilities and construction of new institutional facilities; and other
    operations activities supporting conduct of agency programs.

        Beginning in FY 2002, NASA is implementing a two-appropriation
    budget (excluding the Inspector General account). The two-appropriation
    budget (Human Space Flight (HSF) and Science, Aeronautics and Technology
    (SAT)) is NASA's first step at transitioning to a full cost budget.
    While full cost will ultimately integrate institutional and programmatic
    funds into a single budget, that integration is done in a step-wise
    manner, by providing for a mission support budget line under each
    Enterprise and eliminating the present mission support appropriation.
    This initial step will begin to recognize, budget, and track direct full
    time eqivalent (FTE) personnel associated at the Enterprise level and
    then use this FTE data to distribute other-than-direct (OTD)
    institutional costs (Research and Program Management and non-
    programmatic Construction of Facilities) using the relative percentages
    of direct FTE's by Enterprise.

        This means the distribution of the OTD resources takes advantage of
    a basic assumption, to be used prior to the existence of cost and
    service pools, that FTE's are a reasonable relative indicator at the
    Enterprise level of required facility and institutional capabilities.
    Taking this step will help program/project personnel and decision makers
    begin to understand the potential magnitude of institutional funds that
    are associated with each Enterprise in preparation for the day when full
    cost budgeting will distribute these funds most appropriately to the
    project level via the appropriate cost/service pools.

        The Mission Support budget shown below is shown for display purposes
    only. Beginning in FY 2002, there will no longer be a Mission Support
    account. Institutional costs will be budgeted within HSF and SAT (as
    discussed above) and Safety, mission assurance and engineering will be
    budgeted within the HSF account.

        NASA plans to control personnel levels through full time permanent
    (FTP) civil servant positions while continuing to track full time
    equivalent positions, as done in the past. This will allow NASA more
    flexibility in the use of non-permanent positions for short-term
    technical needs as well as co-op and intern programs.

    Performance Objectives

        Research and program management.--In FY 2000 and FY 2001, this
    activity provides for the salaries, travel support, other personnel
    expenses of the entire NASA civil service workforce, and includes vital
    support to the physical plant at the Centers and at NASA Headquarters.

        Construction of facilities.--In FY 2000 and FY 2001, this activity
    provides for facility construction activities to preserve NASA's
    infrastructure and enable NASA's missions; environmental compliance and
    restoration activities, design of facilities projects, and advanced
    planning and critical functional leadership activities related to future
    facilities needs. Activities in support of construction projects to
    repair, revitalize and modernize the basic infrastructure and
    institutional facilities at NASA centers will continue with the major
    focus on eliminating safety-related concerns. Increasing attention is
    being given to activities in support of environmental compliance and
    restoration requirements.
